What are the components of the drain-waste-vent system?
Your home’s Drain-Waste-Vent plumbing system is the collection of pipes that rid your home of sewage and water waste from toilets, bathtubs/showers, sinks and appliances like dishwashers and washing machines. There are two parts to the DWV plumbing system: drain-waste pipes and vent pipes.
What sort of pipe is used for drain and waste in the household?
The types of home drain pipes that are most typically seen today are either made of copper or the plastics polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS). Other types of drain pipes are sometimes encountered in pre-1960 homes, such as drain/waste/vent (DWV) piping made of iron or steel.
What is the purpose of the trap in the drainage DWV system?
The purpose of this drain trap is to hold standing water, which seals the drain system and prevents sewer gases from rising from the sewer system into your home.
How many types of plumbing traps are there?
03. P, Q and S-Trap. P, Q, and S traps are classified according to their shape. They essentially consist of U – Tube which retains water acting as seal between the foul gas and atmosphere.
How does a primer work on a remote trap?
One of the first lines of defense against trap failure is the trap primer, which is a piping device that helps to maintain a water seal in a remote trap. A trap primer connects to a cold water inlet or other water supply. Every time that inlet or supply is used, a small amount of water flows down to the trap to keep the water seal from drying up.
What does a primer valve do in a sewer trap?
This automatic trap primer valve replenishes evaporated water in floor drain traps to prevent the escape of sewer gases. It has large port openings to prevent clogging from sediment and debris. Water release is factory set — no field adjustment necessary.
Which is the best pressure drop trap primer?
Trap-Defender™ is a pressure drop trap primer designed to be connected to any potable cold water line. It is automatically activated when a valve or faucet is opened and the system experiences a drop in pressure. Water is released into the floor drain’s P-trap to maintain a seal. n Fully automatic, no adjustments needed
How does a trap seal work on a water line?
Trap primers are devices that connect to a cold water line. It is installed in-line. Every time that cold water is used on that cold line, a small amount of water trickles down to the trap that is connected to the trap primer. The small trickle will keep the water seal from drying up.

What kind of primer do you need for a drain trap?
Another type of trap primer can flow water from the potable water system to multiple floor drains/traps. This type of trap primer consists of an automatic timer, electric solenoid valve, vacuum breaker, and a piping manifold with valved outlets, which are each piped to a floor drain trap.
How does a pressure drop activated floor drain primer work?
At this point, a metered amount of water is discharged under pressure into the line connected to the floor drain trap. Pressure drop activated trap seal primers are designed to minimize the problem of clogging. These trap seal primers are constructed with a fine mesh filter, keeping line debris at bay.
Where do you put a trap on a sewer line?
In some cases it exits up from a finished surface, and has a “U” bend. Your main house trap should be directly in front of where the vent connects to your house drain. In some cases, people mistakenly cover or cement over their house trap. As the water flows down the main drain line, air is sucked into the pipe to prevent a vacuum.
